Arizona continues to be clear of Chronic Wasting Disease (CWD), a fatal wildlife disease that affects the nervous system of deer and elk.
Department officials did not find any cases of CWD in the 1,589 mule and white-tailed deer and elk that were sampled in 2020 — the most in more than a decade. AZGFD collected 519 samples from animals that were harvested and voluntarily submitted by hunters, and another 1,070 samples through partnerships with game processors and taxidermists.
AZGFD has been testing for the presence of the disease in Arizona since 1998. While CWD has been found in the neighboring states of Utah, New Mexico and Colorado, the disease has not been detected in Arizona.
The department is grateful for the assistance of hunters who submit deer and elk heads for testing, as well as the cooperation of game processors and taxidermists. For more information about CWD, visit the Chronic Wasting Disease Alliance website.
